Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a cyclodextrin derivative filtration device, including a filter box 1. Inner positioning rings 103 are fixedly connected to the inner walls of both ends of the filter box 1. A rotating disk 502 is rotatably connected to the inner surface of the inner positioning rings 103. A sealing ring 504 is fixedly connected to one side surface of the rotating disk 502, and a filter roller 5 is fixedly connected to one side surface of the sealing ring 504. An inspection port II 503 is provided on the side surface of the filter roller 5, and a filtration mechanism is provided inside the filter roller 5. An inspection port I 101 is provided on the side surface of the filter box 1, and the inspection port I 101 corresponds to the inspection port II 503. A driving mechanism is provided at one end of the filter roller 5, and sealing mechanisms are provided on both sides of the inspection port II 503. Mounting flanges 102 are fixedly connected to both ends of the filter box 1.

[0019] As a technical optimization of this utility model, the filtration mechanism includes a filter element 2, which can filter cyclodextrin derivatives. Both ends of the filter element 2 are fixedly connected to limit rings 201. The limit rings 201 are locked inside the filter roller 5. The limit rings 201 are made of rubber, which can deform when replaced, making it convenient for staff to remove the filter element 2. At the same time, the limit rings 201 can limit the filter element 2 and improve the installation stability of the filter element 2.

[0020] As a technical optimization of this utility model, the driving mechanism includes a bevel gear commutator 3, which is fixedly installed on one side surface of the filter box 1. A servo motor 301 is fixedly connected to the upper surface of the bevel gear commutator 3, and a gear 302 is connected to one side surface of the bevel gear commutator 3 via a rotating shaft. The side surface of the gear 302 is meshed with teeth 501, and the teeth 501 are fixedly connected to one side surface of the filter drum 5. The servo motor 301, the bevel gear commutator 3, and the gear 302 can easily drive the filter drum 5 to rotate, thereby facilitating the replacement of the filter element 2 inside the filter drum 5 or the cleaning of the filter element 2.

[0021] As a technical optimization of this utility model, the sealing mechanism includes a support plate 507, and the support plate 507 is fixedly connected to the side surface of the inspection port II 503. A sealing strip 505 is fixedly connected to one end of the support plate 507. A sealing groove 104 is provided on the inner side wall of the filter box 1, and the sealing groove 104 corresponds to the sealing strip 505, which can further improve the sealing performance of the connection between the filter roller 5 and the filter box 1 and avoid leakage.

[0022] As a technical optimization of this utility model, a support frame 403 is fixedly connected to the other side surface of the filter box 1, and a support rod 401 is slidably connected to one end of the support frame 403. A limiting plate 4 is fixedly connected to the lower end of the support rod 401, and a limiting groove 506 is fixedly connected to the outer surface of the filter roller 5. The limiting groove 506 is symmetrical with the inspection port II 503, and the limiting groove 506 is aligned with the limiting plate 4. The limiting plate 4 at the lower end of the support rod 401 and the support frame 403 and the limiting groove 506 can limit the filter roller 5 and prevent it from rotating during the use of the filtration device.

[0023] As a technical optimization of this utility model, a spring 404 is sleeved on the lower side surface of the support rod 401, and the upper end of the spring 404 is fixedly connected to the lower surface of the support frame 403. The lower end of the spring 404 is fixedly connected to the upper surface of the limiting plate 4. A limiting rod 402 is fixedly connected to the upper surface of one end of the limiting plate 4, and the upper end of the limiting rod 402 passes through the support frame 403 and is slidably connected to the support frame 403. The spring 404 can facilitate the reset of the limiting plate 4 and improve the limiting stability of the limiting plate 4 on the filter roller 5. The limiting rod 402 can limit the limiting plate 4 and prevent the support rod 401 from driving the limiting plate 4 to rotate during use.

[0024] When using this utility model, if the filter needs cleaning or replacement, first close the valves at both ends of the filter box 1. Then, the working heat source pulls the support rod 401 upward. At this time, the limiting plate 4 at the lower end of the support rod 401 disengages from the limiting groove 506. Then, start the servo motor 301 in the drive mechanism. At this time, the servo motor 301 will drive the gear 302 to rotate through the bevel gear commutator 3. The gear 302 will drive the filter drum 5 to rotate through the teeth 501. During the rotation of the filter drum 5, the inspection port II 503 and the inspection port I 101 will be aligned. Then, the operator can take out the filter element 2 inside the filter drum 5 and clean or replace the filter element 2 directly. After cleaning or replacement, the operator starts the servo motor 301 again. At this time, the servo motor 301 will drive the filter drum 5 to rotate back to its original position. Then, the operator releases the support rod 401. Under the elastic force of the spring 404, the limiting plate 4 will be pushed and locked inside the limiting groove 506, thus limiting the filter drum 5.
